I have previously setup this router using a data SIM in a Netgear LM1200 4G LTE Modem for traveling in my caravan. Now I want to hard wire connect the AX72 to my NBN home network and swap out the less efficient existing router.

After connecting the power and then ethernet cable to the WAN port on the AX72, the router begins to cycle up. The first 3 lights turn green, the turns red and the process stops.

When I try to connect a device a message comes up saying Not Connected to Data Network.
